Victoria has 3 times as many buttons as Gillian. Gillian has
23 as many buttons as Min. If the three of them have a total of 99 buttons, how many buttons does Min have?
| Victoria |
Gillian |
Min |
| 3x2 |
1x2 |
|
| |
2x1 |
3x1 |
| 6 u |
2 u |
3 u |
The number of buttons that Gillian has is repeated. Make the number of buttons that Gillian has the same. LCM of 1 and 2 is 2.
Total number of buttons that the three of them have
= 6 u + 2 u + 3 u
= 11 u
11 u = 99
1 u = 99 ÷ 11 = 9
Number of buttons that Min has
= 3 u
= 3 x 9
= 27
Answer(s): 27
